Application filed August 21, 1917. serial No. 187,489.

To all whom it may concern:

\Venham, in the county of Essex and of Massachusetts, have inventedcertain Improvements in Insole-Heel-Seat-Smoothing Machines, of whichthe following description, in connection with the accompanying drawings,is a specification, like reference characters 011 the drawingsindicating like parts in the several figures.

This invention relates to maohmes for a boot or shoe.

It is customary to attach a heel to a shoe by means of nails drivenfrom'the' outside through the heel, the outsole and the insole, the endsof the nails bein fthe shoe on the heel portlon of the insole and beingcovered in the finished shoe by a heel pod, or sock lining. Itfrequently happens that the clenched ends of these heel attaching nailsproject slightly above the surface of the insole and thereby causediscomfort to the wearer of the shoe. The object of the presentinvention is to provide a machine which will effectually smooth and toan extent shape the heel portion of the insole so as to produce acomfortable support for the heel of the wearer of the shoe.

One feature of the invention comprises a shaft, a cutting tool mountedupon the end thereof, a suction conduit the mouth of which extendsaround said tool and serves as a gage to limit the depth of cut of saidtool, and means for rotating said shaft. With this construction the heelseat of the insole may very quickly be smoothed and shaped, the suctionof air through the conduit acting to remove whatever dust or chips areformed and leaving the inside of the shoe clean.

This and other features of the invention, including certain details ofconstruction and combinations of parts, will loe described in connectionwith an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying draw- 1ngs,

The figure is a side elevation of a machine in which the presentinvention is embodied, a shoe being shown in position to be operatedupon. 7

Mounted on. or fast to the head. of the maportion of the insole ofclenched inside chine is a suction conduit comprisinga main Be it knownthat I, BERNARD T. LEvEQUE. a citizen of the United States, resldin attate having a slightly convex cutting face adapted to form aslightdepression in the heel portion of-Ithe insole of a shoe, is fastto the lower end of an uprightshaft 9 ournaled in;

a bearing 11 which is integral with the main portion 3 of the conduit.-The main portion 3 and the end portion 103 are connected by a lap jointas shown to permit vertical adjust ment of the end portion. A screw 13which passes through a slot 15 .in the'end portion and is threaded'intoa boss on the bearing 11 provides means for holding the end portion- 103in adjusted vertical position. A pulley 17 is fastened tothe upper endof the shaft 9 by a pin 19; and a belt 25 runs around this.

pulley, over guide pulleys 27 and around a pulley 29 on the drivingshaft 31.

In the operation of the machine, the conduit is adjusted until the tool7 projects the desired distance below the mouth 5. A shoe is thenpressed up against the tool in the manner indicated in the figurewhereupon the tool smooths and shapes the heel seat of the insole, thedust and chips generated during this operation being carried awaythrough the suction conduit. If after repeated operations the tool'loecomes clogged, a trcadle ll may be depressed to raise a clearingbrush 33 into contact with the tool. The brush is rotatably mounted onone end of an arm 35 which is pivoted to the frame of the machine at 37,the other end of the arm being pivotally connected to a treadle rod 39which is connected at its lower end to the treadle.

It should be particularly noted that the mouth of the suction conduit,by arresting the upward movement of the shoe, serves as a gage todetermine the depth of out of the tool and that thereby a very compactand efiicient construction results.

Although the invention has been set forth in connection with aparticular machine, it should loe understood that the invention is notlimited in the scope of its application to the particular machine whichhas been. shown and described.

Having thus described my invention,

as new and desire to secure by Letters Patent f theUnitd States: v I

1. A m achineof the class described, hav-I 5 ing, in combination,a'shaft, a cutting tool mounted upon the end therepf a stationarysuction conduit the mouth of which extends around. saidtool and servesas a gage to limit the depth of cut of said tool, and

means for rotating said shaft.

f abhineofthe described, havii combination; an upright shaft, a cutonthe eiid theredf,a sta tron conduit through which said theiho'uth (ifsaid conduit exi fl an, s v a a mine the depth of eut of said ans forrhtatin'gsaid shaft.

4, A name (if as: aesdeserib d,hav'- as maa; fliiPfis c ting toolmounted oh-the end thereof, a su'c tion conduit through Which said shaftpasses, the mouth of said conduit extending around said tool and servingas a gage to determine the depth of out of said'toohme'ans for rotatingsaid shaft, and means for producing relative adjustment between saidshaft and the mouth of said conduit.

5. An insole heel seat smoothing machine, having in combination, arotary shaft, 40 an end milling cutter mounted on the end thereof, theconstruction being such that the shaft may be caused to project into ashoe to bring the heel portion of thein'sole there of into contact \viththe cutter,- and a suctioii'conduit having its mouth encirclingthecutter and shaped 'to permit the cutter to operate close to the heel endof the insole.

6. An iiiso'le' heel seat smoothing 1n-'a-' chine, havirig incombination, a rotary shaft, an end milling cutter mounted on the endthereof and shaped as smooth the heel por-- tion of the insole of shoe,a suction conduit adapted to protect the lining of the shoe from theaction of the cutter, and means whereby relative adjustment between thecutter 'ahd the Iriouth of the cohduit may be produced to varythe depthof out made in the insole. I I a V In'testimony whereof Ihave'signed myname. to this specification.
